OSCAR ZERK, 0F CLEVELAND, OHIO, ASSIGNOR, BY IVIESNE ASSIGNMENTS, TO GEORGE W. BOWEN, OF AUBURN, NEW YORK.

WIN GED CAP.

Application filed July 31, 1913.

To all whom it may concern:

Be it lmown that I, OSCAR ZERK, a subject of the Emperor of Austria, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Winged Caps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings. Y

'Ihe object of this invention is to' provide a winged cap suitable for grease cups and similar articles so constructed that it may be very cheaply manufactured, and, at the same time, be eiicient in service and neat in appearance. To this end I make the cap of two parts, the cap proper, and the wing, which is secured to the cap by upsetting a portion of the wing into an opening in the top of the cap. The invention is hereinafter more fully explained and its essential characteristics set out in the claim.

In the drawings, Figure 1 is a side elevation of my ca Fig. 2 is a vertical central section thereo Fig. 3 is a perspective view of the` wing removed; Fig. 4 is a cross section through the wing and a portion of the cap.

As shown in the drawing, 1 represents the cap, which has a cylindrical wall internally threaded at 2 and is provided with a flat, circular top 3. 5 indicates the wing, which is a at bar of metal having one or more lugs 6 extending from the under edge of the wing. These lugs (of which two are shown in the drawings) extend4 through openings in the top 3 of the cap and are upset to lock the wings to the cap. The under edge of the opening which the lugs Specification of Letters Patent.

Patented Oct. 16, 1917.

serial no. 782,180.

occupy is preferably chamfered or countersunk to enable the upsetting to be Hush with the under face of the top 3, shown in Figs. 2 and 4.

To eifectively brace the wing and add to the neatness of appearance, I provide, at its side just above the lugs 6, flanges 8. These flanges are flat on their under side and flush with the under edge of the wing. On their upper sides the flanges are preferably concavely flared to merge with the sides of the wings, as shown.

WV hen my winged cap is completed, it presents substantially the same appearance and action as if the wing and cap were made from an integral casting, but the construction is very much cheaper. My cap may be very conveniently made by stamping in accordance with the process described and claimed in my Patent No. 1,048,261, granted December 24', 1912.

Having thus described my invention, what I claim is:

CII

A cap havingva body portion formed with a top provided with a perforation or perforations and a wing resting on .the top and having a lug or lugs projecting from its lower edge and extending through the perforation or perforations, the wing having flanges on opposite sides of vits lower edge, overlying the top face of the cap, substantially as and for the purpose specified.

In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
